Pazuzu

Two weapons are kept in this land.
One lies beyond Pazuzu's guard.
The other lies in the Serdab of Light, which extends from the pit of flames.
--Priest Gailious

A monster with the body of a human, the head of a dog, bird wings and a mane. Has an unusually high body temperature, so much so that it burns humans on touch. Creates blasts of hot air, throwing burning rocks at intruders.
--Vita version bestiary

This strategy works with Shurikens too, if you don't have the Chakram. You can get 3 hits in every time from the moment Pazuzu flies to the centre of the room until the moment he throws a boulder. This will take a lot of ammunition, but it is a safe way to get the chain whip early.

Alternative way is to stand to the right of a fallen boulder and hit Pazuzu with Axe when he flies to grab it and run off to dodge the boulder. While tiresome, this is a relatively safe method, since you are guaranteed to hit Pazuzu while having time to dodge his throw and being safe from colliding with him.
